Combined loss of LAP1B and LAP1C results in an early onset multisystemic nuclear envelopathy

Abstract

Nuclear envelopathies are a group of diseases caused by genetic mutations in essential nuclear envelope genes. Here, the authors report a nuclear envelopathy with a homozygous nonsense variant in TOR1AIP1 which leads to changes in the nuclear morphology including large nuclear-spanning channels in patients’ fibroblasts.
